State-of-the-Art for Assessing Earthquake Hazards in the United States, Report 25: Parameters for Specifying Intensity-Related Earthquake Ground Motions

Description: Abstract: "A set of 12 charts are presented that relate Modified Mercalli intensity units to peak horizontal acceleration, velocity and duration for near field and far field locations, hard and soft sites, and sizes of earthquakes. Also shown is the mean, mean plus one standard deviation, mean plus two standard deviations, and the highest observed values. Ratios are provided of vertical to horizontal motions and predominant periods. These charts are for use with known fault sources and for floating earthquakes in zones where there are no identifiable causative faults. The procedure provides parameters for shaping time histories to be used for dynamic analyses."

State-of-the-Art for Assessing Earthquake Hazards in the United States, Report 28: Recommended Accelerograms for Earthquake Ground Motions

Description: Abstract: "A catalog of recommended accelerograms and response spectra is provided to accompany all representative values for Richter magnitudes at distance determined peak horizontal accelerations-velocities-durations, hard and soft sites, shallow and deep earthquakes. Accelerograms are also recommended for corresponding Modified Mercalli intensities. The accelerograms are related to the Krinitzsky-Chang-Nuttli curves for magnitude and distance, and the Krinitzsky-Chang curves for MM intensity."

State-of-the-Art for Assessing Earthquake Hazards in the United States: Report 19, The Evidence for Reservoir-Induced Macroearthquakes

Description: Partial abstract: "The published evidence of reservoir-induced macroearthquakes is critically reviewed. The evidence is partitioned into three types: (a) evidence of a post-impoundment increase in seismicity, (b) correlation evidence that is composed of a plot of a reservoir variable and a seismicity variable and, in most cases, an auxiliary variable, time, and (c) evidence based on the slope of the magnitude-frequency relationship (b value evidence)."

State-of-the-Art for Assessing Earthquake Hazards in the United States: Report 11, Imagery in Earthquake Analysis

Description: Partial abstract: "Recent advances in the fields of remote sensing, engineering geology, seismology, and earthquake engineering have developed a need for a systematic comprehensive review of the basic principles and methods of applying remote sensing for evaluation of earthquake hazards and seismic risk. This paper responds to this need by reviewing basic concepts, summarizing essential, state-of-the-art knowledge of theory and instrumental methods, establishing procedures evaluations, and discussing representative case histories that illustrate earthquake hazard evaluations that are based on remote sensing analysis."
